OIL-BURNER.

Application filed May 21,

To all whom it may concern:

Be it known that I, LOUIS M. KOHNER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Oil-Burners, of which the following is a specification.

This invention relates to an oil burner and pertains to the type of burners especially adapted for use in the fire boxes of cook stoves, ranges, and the like, for burning kerosene and other hydrocarbons of the heavier varieties, and more particularly pertains to the class of liquid fuel burners in which the liquid fuel is delivered to a generating tube disposed above a baflie plate and converted into vapors by the action of flames directed against the generating tube bythe baffle plate.

In burners of the above character it is desirable to obviate as far as possible the formation of carbon within the generating tube which is usually caused by excessive feeding of oil to the generator, and it is the object of this invention to provide a construction whereby this may be accomplished.

Another object is to provide means wherebyinitial generation may be readily and economically efiected and also to provide means for collecting such unburned portions of the fuel as may from any cause be discharged from the, generator. 1

Another object is to provide means for shielding the flames against drafts at their point of formation to minimize the danger of their'being blown out, and at the same time to provide means for facilitating admixture of air with the'hydrocarbon vapors at their point of combustion.

Other objects will appear hereinafter.

- The invention is illustrated in the accompanying drawings, in which:

Figure 1 is a view of the burner as seen in side elevation, with portions broken away.

Fig. 2 is a view in perspective illustrating the burner shield removed.

big. 3 is a view in end elevation showing the burner with the shield removed.

Fig. 4c is a detail plan view with the generator removed showing the baffle plate, flame spreader, and generating cup.

More specifically, 5 indicates a feed pipe leading from any suitable source of hydro carbon supply on the upper end of which a Specification of Letters Patent.

screwed on the ends of the generating tube;

the threadson the generating tube and the elbows being right and left, the lower por tion of the generating tube. including the T coupling 6 at the elbows 8 form a fuel storage and gaslfying chamber. Any other form of connection between the supply pipe and the arched generating tube which will form a fuel storage and gasifying chamber may be provided as may be expedient.

In carrying out my invention the gener- Patented Sept. '7, 1920. W

ating tube is disposed at an incline to the T horizontal as particularly shown in Fig. l, and formed on the under side of the connectlng end portion of the tube is a discharge orifice 11 arranged so as to discharge downwardly either on the perpendicular or at an incline, the direction ofdischarge being subject to regulation. by adjusting the inclination of the generating tube.

Disposed beneath the generating tube is a baflle plate 12 upon which flames from the burner are projected, this baffle plate being .adjustably mounted relative to the generating tube to vary its position in spaced relation to the discharge orifice.

[The means here shown for-effecting .vertical adjustment of the bafile plate embodies a sleeve 13 slidably mounted on the pipe 5 on which the baflie plate is carried. A set screw 14: is screwed in the sleeve 13 to engage the pipe 5 and hold the sleeve and the bafiie plate in position.

,Formed in the connection between the baflle plate' and thesleeve is a generating cup 15 extending beneath the lower portion of the generating tube in such position that .on ignition of a generating fluid therein the .fiames will be directed against the generator at its point of intersection with the feed pipe.

An overflow pipe 16 connects with the side wall of the generating cup and leads to any suitable point of discharge to take care of surplus liquid fuel which may be delivered to the cup. 7

purpose of spreading the flames directed upon the baffle plate the latter is formed 'with a central rib 18 having inclined side walls; the rib being disposed between the channels 17 and directly beneath the discharge orifice 11.

As a means for protecting the flames against being extinguished by drafts a shield 19 is provided which is here shown as formed of sheet metal of such shape as to seat upon the outer portion of the generw ating tube, and as embodying the top wall 20, dependent side walls 21, and an end wall 22; the top wall being formed with downturned flanges 23 forming with the side walls 21 saddles adapted to seat on theside portions of the generating tube. The side and end walls of the shield are formed with perforations 24 for the admission of air to facilitate admixture of air with hydrocarbon vapors discharged from the generating tube.

In the operation of the invention initial generation may be effected in any desired manner, preferably by igniting fuel in the generating cup so as to heat the lower portion of the generating tube sufiiciently to convert hydrocarbon fuel therein into vapors; the fuel being delivered to the generator through any suitable means of control. The vapors formed in the generator are dischargeddownwardly therefrom and mixed with air beneath the shield, and on being ignited the flames will be directed against the baflie plate and spread thereby. A portion of the flames will be directed against the lower part of the generating tube to continue the generatingaction. v o

By adjusting t e baffle plate relative to the generator the point of impact of the flames against the generating tube and the intensity of their contact may be varied to suit conditions, and by this arrangement the generator may be subjected to the action of only such flame as is necessary to effect proper vaporization of the hydrocarbon fuel so as to prevent overheating of the hydrocarbon fuel and thereby minimize the formation of carbon within the generator.
